So in reading these forums no one is happy with their changes...every class want to be overpowered and stomp on everyone else. I'm included in this group with the rogue nerfs to crit. (not sure what you are thinking trion).
SO...to be constructive here is the fix to all these problems.
After 1.5 is done SWEAR to all of us that no more class changes will happen. It is what it is.
THEN give everyone a 1 time FREE class and faction change. Any gear the person has on will be refunded in an appropriate amount of Runes/Favor, etc., to buy the same level of gear.
Feel another class or faction is overpowered. Here is your chance to join them.
